Question

In Angle abc and angle pqr ab:pq=4:5 and a(angle pqr)=125cm² then find a(angle abc)

Answer 1

Therefore, the measure of angle ABC is 55 cm².

Explanation:

In order to solve this problem, we need to use the property of angles in a linear pair, which states that the measures of the two angles in a linear pair add up to 180 degrees.

If angle ABC and angle PQR form a linear pair, then the measure of angle ABC is 180 degrees minus the measure of angle PQR.

Since the measure of angle PQR is 125 cm² and the measure of angle ABC is 180 degrees minus the measure of angle PQR, the measure of angle ABC is:

180 degrees - 125 cm² = 55 cm²
